Answer:

Option C

Step-by-step explanation:

16 ounces = 1 pound

Cost of blueberries at grocery store, 8 ounce = $2.80

8 ounce =  \frac{8}{16} = 0.5 pound

Cost of blueberries at grocery store per pound = \frac{2.80}{0.5} = $5.60

Cost of blueberries at farmers market, 14 ounces = $4.20

14 ounces =  \frac{14}{16} = 0.875 pounds

Cost of blueberries  at farmers market per pound = \frac{4.20}{0.875} = $4.80

Per pound cost of blueberries at grocery store = $5.60

Per pound cost of blueberries at farmers market = $4.80

Difference between the cost = 5.60 - 4.80 = $0.80

So the option c is accurately compares the cost of blueberries. " Blueberries are $0.80 per pound less expensive at the farmer's market.

Grocery store : 2.80/8 = 0.35.....so its 35 cents per oz.----0.35(16) = 5.60 per lb
farmers market : 4.20/14 = 0.3...so its 30 cents per oz --- 0.30(16) = 4.80 per lb

5.60 - 4.80 = 0.80.....answer is : blueberries are 80 cents per pound less expensive at the farmers market

J.k. Rowling and R.L. Stone are both ready hunger games . J.k. Reads 35 pages every 2 hours and R.L. Reads 45 pages every 3 hour
san4es73 [151]

Answer:

The rate of change for each reader is :

For J K Rowling :  17 and a half pages per hour

For R L Stone :  15   pages  per hour

Step-by-step explanation:

Here the reading rate of each reader is given as:

J.K. Reads 35 pages every 2 hours.

So, the number of pages read by J K  in 2 hours  = 35 pages

⇒ The number of pages read per hour  =  35 / 2  = 17 . 5 pages

So, the pages read by J K Rowling in 1 hour is 17 and a half pages.

R L Stone reads 45 pages every 3 hours.

So, the number of pages read by R L  in 3 hours  = 45 pages

⇒ The number of pages read per hour  =  45 / 3  = 15 pages

So, the pages read by R L Stone in 1 hour is 15 pages.

Hence, the rate of change for each reader is :

For J K Rowling :  17 and a half pages  per hour

For R L Stone :  15   pages  per hour

What is the solution to the system of equations?<br><br> 6x – 9y = 16<br><br> 2x – 3y = 7
kifflom [539]
The first step for solving this problem is to multiply both sides of the bottom equation by -3.
\left \{ {{6x-9y=16} \atop {-6x + 9y = -21}} \right.
Add the two equations together.
6x - 9y - 6x + 9y = 16 - 21
Eliminate the opposites.
-9y + 9y = 16 - 21
Remember that the sum of two opposites equals 0,, so the equation becomes the following:
0 = 16 - 21
Calculate the difference on the right side of the equation.
0 = -5
This means that the statement \left \{ {{6x-9y=16} \atop {2x-3y=7}} \right. is false for any value of x and y. That means that the answer to your question is (x,y) ∈ ∅,, or no solution.
Let me know if you have any further questions.

Choose the expression that represents a quadratic expression. 9x − 2 5x2 9x − 1 −2x3 8x2 − 7x 1 x4 − 12x3 8x2 − 7x 1
NikAS [45]

<u>5x² + 9x - 1</u><u> is  the expression that represents a </u><u>quadratic expression</u><u>.</u>

What is  quadratic expression?

  • Quadratic expression is an expression with the variable with the highest power of 2.
  • The word quadratic is derived from the word quad which means square.
  • The expression should have the power of two and not higher or lower.

A quadratic expression is of the form

ax² + bx +c = 0                    where a ≠ 0

The give options are-

9x - 2

5x² + 9x - 1

-2x³ + 8x² - 7x +1

x^{4} - 12 x^{3} + 8x^{2} - 7x +1

From the given options, the only expression which is quadratic is

5x² + 9x - 1

wChoose the expression that represents a quadratic expression. 9x − 2 5x2 9x − 1 −2x3 8x2 − 7x 1 x4 − 12x3 8x2 −here a =5, b=9 and c=-1

Therefore, 5x² + 9x - 1 is  the expression that represents a quadratic expression.
